All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.
The nucleus of boron-11 contains 5 protons and 6 neutrons.
5
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
The atomic strucutre and the sub-atomic particle. It place is according to how many shells it has and how many electrons in its outer shell. A new row on the table show a new shell on the element. The atomic number( the bottom) show the number of protons the neuclus has, and the atomic number(top one) shows how many protons and neutrons the atom has together this can be used to see if an isotope is made
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
5 electrons as its atomic number is 5.
Atomic number = 5So there are 5 electronsAtomic number=protons=electrons
5 Electrons and 5 Protons
Five. The Atomic Number of Boron is 5 so it has five protons and 5 electrons. The Mass number of Boron is 11. Mass minus atomic number = number of neutrons = 6. BORON:Electrons = 5 Protons = 5 Neutrons = 6
A neutral boron atom has 5 electrons. On the periodic table, the atomic number of boron is 5. This means that all boron atoms have 5 protons in their nuclei. Protons are positively charged, and electrons are negatively charged, therefore, a neutral boron atom has 5 protons and 5 electrons.
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
Boron's atomic number is 5. So there are 5 protons and 5 electrons. In Boron-10, there are 5 neutrons (10 - 5 = 5)
Boron's atomic number is 5. Thus, its electron configuration is 1s2 2s2 2p1. If you add up the number of electrons in the "2" shell, which is boron's valence shell, you get 2 + 1 = 3 valence electrons.
3
Boron's atomic number is 5. Thus, it has 5 protons per atom. To be electrically neutral then, it must also have 5 electrons per atom.
5 Protons,6 Electrons,5 Neutrons
